Namespace:  System.Web.UI.WebControls

virtual property bool AutoPostBack {

Property Value

Type: System::Boolean
true if a postback to the server automatically occurs whenever the user changes the selection of the list; otherwise, false. The default is false.

Set this property to true if the server needs to capture the selection as soon as it is made. For example, other controls on the Web page can be automatically filled depending on the user's selection from a list control.

This property can be used to allow automatic population of other controls on the Web page based on a user's selection from a list.

The value of this property is stored in view state.

This property cannot be set by themes or style sheet themes. For more information, see ThemeableAttribute and ASP.NET Themes and Skins.

The following example demonstrates how to enable AutoPostBack for the ListBox control.
